STOP FOR TALKING-MACHINES.

Patented Dec. 28, 1915.

Continuation of application Serial No. 684,720, filed March 19, 1912. This application filed May 17, 1912.

' Serial No.697,936.

' vide a simple, compact and reliable attachment for existing machines,

and especially those of the flat-disk type, secondly to simplify the operation of setting the stop to release the record-support at the beginning of a selection, and thirdly to provide means for quickly and easily setting the device so as to control the time of its stopping action to correspond. with the point at which the se- 7 lection ends.

A further object of my invention is to furnish improved means whereby the brakecontrolling latch may be automatically set in brake releasing position by the manual movement of the reproducer to position it at the beginning of the record groove, one of the advantages attained being that the resetting mechanism does not necessarily involve any friction or pressure on the reproducer arm or other parts of the reproducing structure during the performance of a selection, and is so combined with the stop as to ermit the positioning adjustment of the atter,- and the tripping of said stop with very slight exertion of power.

The present application is a continuation of my application Serial No. 684,720, filed March 19, 1912.

Of the accompanying drawings, Figure 1 represents a plan view of a talking machine provided with automatic stop mechanism constructed according to my invention. Fig. 2 represents an elevation of the stop mechanism,partly in section. Fig. 3 represents a cross-section on the line III-III of Fig. 2. Fig. 4: represents an end elevation and section looking in the opposite direction from Fig. 3. Fig. 5 represents a plan view showinga modification. Fig. 6 represents a side elevation-thereo Fig. 7 represents an end elevation beyond its catchingposition,

Referring at first to Figs. 1 to 4 inclusive, 10 indicates a base having a bearing 11 in which is mounted a slidable brake stud 12 having a cam 13 on its rear or outer end.

14 is a brake-operating lever pivoted at 15 on suitable standards on the base 10 and adapted to be depressed by its weight and a pair of springs 16, said lever carrying a spring arm 1?: provided with a cam 18 adapt .ed to act against the cam on the rear end of the brake stud.

19 is a re-setting arm hung on pivot 15 and having a projection 20 engaged bv an adjusting screw 21 on the lever 14, so that the angular relation of said lever and arm may be varied, the l e-setting lever having a roller 22 at its outer end adapted to be engaged by i the reproducer arm 23 when the latter is carried outwardly to the beginning of a selection. v

24 is a standard formed with dove-tailed horizontal guides 25 in which is mounted a normally fixed but adjustable keeper slide 26 provided with a knob or handle 27. said slide being laterally pressed against by a leaf spring 28 to furnish friction.

On the keeper slide 26 is mounted a latchtripping slide 29 having a roller 30 at its end, in a position to be encountered by the .reproducer arm at the completion of a selection, slide 29 being suitably guided to move longitudinally on slide 26 and loosely held thereon by pins 31 operating in holes 32 in the upper slide which allow some play to the latter.

33 is a vcrtically-movable latch bolt having a sliding fit in a guide bearing in the slide29'and extending loosely through an aperture in the keeper slide 26, said latch bolt having a shoulderBl: adapted to take over the edge of the hole in the keeper plate 26 through which the bolt passes, said bo'it also having a cam pin operating against a cam incline 36 when the bolt is forced into its uppermost pgsition, whereby its shoulder 34 is caused to overlap the keeper slide and retain the bolt in elevated position, such lateral movement'and engagement being effected by carrying the bolt upwardly slightly and then allowing it to'descend until the shoulder 34 rests bathe keeper slide.

The lower end of the latch bolt is formed with a T whose head 37 engages the under side of the lever 14 and whose neck occupies an elongated slot 38 which permits the latch boltto remain in engagement with lever 1 1 when the keeper slide 26 is adjusted to position the stop with respect to the completion oi: the record groove, said slot being openended, as seen in dotted lines in Fig. 1, to permit the assembling of the device. The. upper side of lever 1 1 is adapted to engage with shoulders 39 on the latch bolt to elevate the latter. In operating this em bodiment of my invention, the reproducer arm 23 is placed as represented in full. lines in Fig. 1, so that the needle will be in or about the last or innermost turn of the record groove, and then the keeper slide 26 is pushed by means of its handle 27 to bring the roller 30 against the side of the reproducer arm. Then when said reproducer arm is carried outwardly to or somewhat beyond the dotted line position indicated in Fig. 1 preparatory to positioning the needle in the outer portion of the record groove it acts against roller to depress the resetting arm 19 and raise the lever 1+1 and the spring arm 17 carried thereby, thereby releasing the brake 1:2. The brake-stud slides free] y in its guide 11, and when the pressure of spring: arm 17 is removed, the turn-table is thereby allowed to rotate. The lever It raises the latch bolt until its shoulder 34 takes over the keeperslide 26, the bolt being forced laterally by the cam members 35, 36 and allowed to descend into latching position as described, and this slight longitudinal. movement of the slide 29 produced by the lateral movement of the bolt 33 will cause the roller 30 to be positioned so that it will be encountered by the reproducer arm several turns of the record groove before the end of the lat ter, which turns being blank ones on the ordinary record, will allow the necessary margin of movement to the reproducearm at the completion of the selection to dislodge the bolt 33 from the keeper slide 26 and allow lever 14 to drop with the assistance of the springs 16 and cause the brake 12 to be set by theaction thereon of cam 18.

In Figs. 5, (3 and 7, I have represented a modificationin which 12 represents a pivoted brake-lever, 33 a vertically-movable latch bolt engaging one arm of said lever, 26 a keeper plate trictionally pivoted upon a post .24, and 29* a latch-operating lever loosely pivoted on said post, other parts correspond ing to those in Figs. 1 to 4 inclusive being designated by like reference characters, and the action of the members 14, 19 in re-setting the latch bolt being the same as above set forth.
